You may recall that recently NASA launched a new craft, the Solar Dynamics Observatory, to explore the science of the sun by making measurements of unprecedented resolution. Well, images have been released from it for the first time and they are truly spectacular! The one above is featured prominently in the extensive Click to continue reading this post →

And So It Goes…

bottega_louie_2So it has been a quiet week or few in my immediately local world. This is by choice. Recall that I’m on sabbatical, and working on a project. I’m trying to work on it exclusively, but I keep getting interrupted by several other things, especially since I returned from Walkabout.

But I do what I can, saying no to some things, doing some duties where I am needed, and tending somewhat to my private life and friendships of course. But mostly I’ve been hiding and working on the project. Overall, I can report that I’m very pleased with progress in the last month (since I returned to LA) on several aspects of the work. I’m sorry that I have not – and still will not – tell you anything about the project. I’ve already given my reasons, and nothing has changed. Perhaps later.

Most of my work has been in Away mode, which means at offices other than the one assigned to me at work. I am certainly staying away from the department as much as I can, (no disrespect intended, but people find things for you to do if you’re perceived as being around – I am not around!), and the same goes for the campus, making only fleeting visits to the latter, mostly in stealth mode (my obligatory sabbatical beard, among other things, has helped here). Sometimes I appear for a Click to continue reading this post →

Categorically Not! – Imagine

yossi_govrin_sculptureThe next in the Categorically Not! series the series of events is tomorrow, Sunday 18th April. It is, as usual, held at the Santa Monica Art Studios. It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events. (At the right is an image of a beautiful sculpture by artist Yossi Govrin, who is on this week’s program.)

The theme this month is Imagine. Here’s the description from K. C. Cole:

Hoping for a Triumph of Substance over Style

…perhaps I am naive. Going to follow (listening online I imagine) the UK’s first ever prime ministerial televised debate. I’m very concerned that it is going to make the UK electorate focus even more on nice suits and good hair and less on knowledge and ideas, following the lead of other countries. But I am hoping. I’m holding out some faith in my countrymen…

Singh Case Over!

By | | ,
3 Comments

Excellent news. The libel case against Simon Singh has been dropped. BBC story here. (See my previous post for details.)

Most important quote is from Simon:

Dr Singh said he was hugely relieved, but expressed his annoyance that libel actions continued to be used to block what he viewed as legitimate scientific inquiry and debate.

“Other scientists, science writers, bloggers, investigative journalists, human rights activists – all get threatened with these libel suits,” he told BBC News. “And at the end of the day, the people who lose out are the general public because we don’t get to find out the real truth because these libel suits just stop good journalism.”

Very true, and there is much work to do on that aspect of the legal system, but for now, beers all around, ok?!

hobys_rosette_05 This is a wonderful infrared image (please click on it for lovely larger view) of a region of star formation called the Rosette Nebula.

It comes from the Herschel space observatory, which was launched (along with the Planck observer) by the European Space Agency (ESA) almost a year ago, you may recall.

From the ESA website, here’s a bit more about what this is:

Mount Wilson Open For Business!

Good News Everyone!

flames near mount wilson seen from atwaterYou may recall the terrible fires of last year in the San Gabriel mountains, and the scare about whether the Mount Wilson facility might have been overrun by flames. There were Tolkienesque scenes of flaming mountains, dramatic battles on mountaintops, and so forth. No Balrogs were involved (a far as I know), but it was nail-biting enough for many.

One of the fallouts (fallsout?) of this was that the public access to the Observatory needed to be suspended. This included the ability to reserve access to the famous 60 inch telescope for your own use for an evening, an activity that I have highly recommended (from first hand experience) here on the blog.

Well, I can happily announce (I heard this from my friend Shelley Bonus who works Click to continue reading this post →

Calla Lily!

calla_lily I’m very pleased to see this flower (and always delighted to say the name out loud: Try it: Calla Lily.). (Click for larger view.) I discovered a patch of shoots growing in the shade of a tall tree some time ago, struggling against a thriving ground cover plant, and decided to clear some space for them and let them grow up, giving them a supply line off the drip system. That was a year ago. Now, they’re nice and large, and Click to continue reading this post →

Riverside Fun

(Note: Written yesterday afternoon at 6:00pm.) Well, that was fun! I am on my way back from UC Riverside where I visited to give a colloquium. I met a number of faculty that I had not seen since I was last there (talking at a DPF APS meeting in 2004) and people seemed to like the talk (similar to the ones I gave last Fall in LA and in Vancouver), even though I was a bit rusty in my talk-delivery, being deep in sabbatical mode, you understand. I wallowed too much in the experimental physics part of the talk and so had to rush the ending bits where I bring in aspects of string theory to the game. I hope people were not too confused. I invited people to send me email for more information/explanation if they wanted to, since I had to leave immediately after my talk.

You might be wondering why I am typing while I’m driving on the highway. Isn’t that bad? I could respond that texting while driving is illegal but blogging while driving is perfectly fine (along with things like eating, shaving, applying makeup, and a host of other things you see people doing in cars, some of which I won’t mention as this is a family blog). However I won’t make such a silly response since of course I am not driving. I took the train. Yes, I’m weird. It’s a very fine double-decker (actually there Click to continue reading this post →

Other Accelerator Physics is Available

The alternative title for this post was going to be “Closing in on Unobtanium”, but I realized that it might be better to explicitly remind you that the Large Hadron Collider, understandably featuring in the news a lot these days, is not the only particle accelerator in operation. Such machines are routinely at work all over the world (for example, supplying hospitals with radioactive materials used in medical diagnosis), and doing various kinds of key research (recall as another example the RHIC physics I’ve told you a bit about in relation to certain applications of string theory). One such set of investigations involves finding new heavy elements, extending the periodic table of elements. Yes, just like happened with Pluto’s demotion and its resulting effect on your internalized list of planets in the solar Click to continue reading this post →

She Blinded Me With Science…

The funny video below* is good for a bit of nostalgia for the time of the Thomas Dolby song, the song itself, and perhaps for the X-Files TV show (but not for me, I saw only a few episodes). Scully fans will love this, and although I never regularly watched the show, I did appreciate her character. Strong skepticism, insistence on using the scientific method, etc. Excellent. Good character overall, and broke a lot of ground as a female lead with these characteristics too.

chloe_obrian_24Now here’s an idea. Would someone please do such a video for 24’s Chloe O’Brian? (Pictured left.) She’s definitely one of my favourite technical expert engineer/scientist types on a major show, and Mary Lynn Rajskub does an excellent job giving her life, depth and likeability even though she’s fighting against all the geek/nerd stereotype characteristics they’ve endowed her with. In essence, she does it by embracing them. Her attention to detail regularly saves the day (world, city, state, whatever), and the lives of her colleagues, and in the last episode they even had her supposedly determining that light in a video was daylight by Click to continue reading this post →

Occult Activity Tonight!

rws_zetaophocc1Oh yes. Occult. Exciting right? Those of us in LA and some other areas (apparently points in Nevada, Idaho, and Western Montana, and the cities of Calgary and Edmonton) will see have the chance to see something quite remarkable if we stay up until 03:34 Pacific time (i.e., early morning April 6th). I learned this from Phil’s blog. You can find out more from Sky and Telescope (that’s their figure on the right). The event is this. If you stare at the star ζ (Zeta) Ophiuchi, which is visible to the naked eye, it will go dim for about eight seconds. Why, because an asteroid (824 Anastasia) will pass directly in front of it. You can’t see the asteroid directly, since it is too small and too dim, but nevertheless its presence between you and the distant star will be enough to make it go dim for a bit. Isn’t that wonderful? Have a go!

This remarkable effect (called occultation – hence the sneaky blog post title: the key root meaning here is “hidden”), while it might seem rather mundane in some ways (although you’re seeing the effect of an asteroid with your own eyes!) is extremely powerful in astronomy. It is a great way, for example, of detecting planets orbiting other stars! You’re familiar with occultations already actually. When the moon moves Click to continue reading this post →

obama_light_sabreI’ve never been one for the naive Obama-gushing, you may have noticed, but I can’t resist this lovely tribute. It is the site called “President Obama Looking at Awesome Things”, a collection of “photos”, and the example to the left is one of my favourites. (Click for larger view.)

It is excellent use of certain looks he gets on his face when doing things like “looking interested” at things. Isn’t photoshop great?

jaime_escalante_by_robert_gauthierYou might not have heard of him, so I thought I’d mark the passing, on Tuesday, of the mathematics teacher Jaime Escalante. (Photo on right by Robert Gauthier.) He was an extraordinary teacher who passionately believed in the abilities of the many East Los Angeles students from disadvantaged and traditionally ignored backgrounds that he taught, enduring the ridicule of his colleagues to press on with the job of teaching them as well as he could, challenging them to reach impressive heights of mathematical ability, especially considering given the circumstances.
